This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this activity (on pages 22-24 of the PDF), learners match extreme enviroments with life forms they support.

In this optics activity, learners make a simple telescope using two lenses and a cardboard tube. Learners construct the telescope and then calculate its magnification.

In this group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

This activity (on pages 10-12 of the PDF) encourages learners to consider what makes living things different from non-living things.

In this activity (on pages 19-21 of the PDF) learners observe mold growing on potatoes. Preparation for this activity has to start a week before, to allow time for the mold to grow on the potatoes.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

“Exploring the Universe: Imagining Life” is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.
